External beam radiation therapy (EBRT) is a type of radiation therapy that directs a beam of radiation from outside the body onto cancerous tissues within the body. EBRT delivers high-energy rays to tumors, using a special X-ray machine called a linear accelerator. This machine allows radiation to be delivered from any angle and shapes radiation beams to the contour of the tumor.
External beam radiation is distinguished from internal radiation therapy, which places radioactive materials directly into or near a tumor via injection, a catheter, or other methods.
Advantages of External Beam Radiation Therapy
Our state-of-the-art radiation technology enables our oncologists to more accurately target a tumor with higher doses of radiation, while minimizing damage to your healthy tissue and nearby organs. As a result, EBRT helps to lower the risk of side effects typically associated with radiation treatment.
- It’s a fast, painless outpatient procedure. A typical radiation treatment lasts a few minutes. It is administered over a period of six to eight weeks, typically five days a week.
- It does not carry the standard risks or complications of surgery, such as surgical bleeding, post-operative pain, or the risk of stroke, heart attack or blood clot.
- Unlike chemotherapy, which circulates through the body, ERBT is targeted to the area being treated.
